For instance, if test001A.txt is this file:
and test001E.py is this:
f = open('test001A.txt', 'r')
for line in f:
then the output from "python test001E.py > temp.txt" is this:
and indeed the output from "print repr(f.read())" is this:
'abc xyz\nBd ef\n\ngH ij\n'
How do you actually get to see the raw bytes of a file in Windows?
OK, this seems to work:
f = open('test001A.txt', 'rb') # Binary mode
'abc xyz\r\nBd ef\r\n\r\ngH ij\r\n'
Indeed, when a Windows file is opened for reading in binary mode,
the length of an "empty" line is returned as 2. This is starting
to make some sense to me now.
